Industrial Ethernet for Position Feedback: PROFINET vs EtherCAT
Industrial Ethernet includes PROFINET (199) and EtherCAT (197/198). Choose by the PLC master, not by which name sounds newer.
Magnetostrictive displacement sensor knowledge base: principles, selection, installation, accuracy and materials

Industrial Ethernet includes PROFINET (199) and EtherCAT (197/198). Choose by the PLC master, not by which name sounds newer.

Serial fieldbuses include 194 CANopen and 195 Profibus DP. CAN’s physical layer is not RS-485. Compare the trade-offs, then follow the master.

Series 16 SSI is 162; Series 19 SSI is 192. Bit length, D70, baud vs cable and 48 μs clock spacing are the same; mounting and pressure are not.

16T is one magnet acting on three independent waveguides and electronics — not three sensors. Do not mix it with 16R dual-channel. Pressure stays 350 / 530 bar.

16E keeps the Series 16 cap Ø18G7 and 350/530 bar. What is upgraded is the IP68 fully enclosed housing — not a different pressure rating.

The Series 19 analogue programmer 1700 951 018 changes zero and end on the sensor. PLC two-point (Slope / Datum) is a different layer. Do not turn both at once.

Pick the connector family by output: Series 12 DIN 43650, 162/192 SSI D70 seven-pin, 191/194 often D60 six-pin, EtherCAT and mobile hydraulic often M12. Wrong pin count means no comms or a burned analogue head.

Electrical outputs by series: Series 16 is 160 voltage / 161 current / 162 SSI; Series 18 is 180–185; Series 19 is 190–199. 162 is Series 16 SSI; 192 is Series 19 SSI — do not mix them.

An injection molding machine normally needs position measurement at three points — injection, clamping and ejection — and more on high-end full closed-loop models. This article sets out how many displacement sensors each station needs and how to select them.

The first criterion for protocol selection is the master system; only then do synchronization requirements, segment length, diagnostic needs and cost come into play.

The five cylinder-integrated models share the same performance; select by filtering through three layers — explosion protection, redundancy and integration method — while sharing three constraints: bore, pressure rating and oil temperature.

The four external types are judged on three levels — environmental rating, stroke length, and platform and follower structure — with misalignment and bracket resonance as shared risks.

The 19D separates the electronics head from the measuring rod, solving the problem of a measuring point whose environment exceeds what electronics can withstand — the connecting cable is the critical part.

The flexible rod of the 19F breaks through the three bottlenecks of rigid designs — deflection, transport and straight-line path — suiting gates, rolling mills and other very long strokes.

Both the 19P and 18 are rigid external types with identical performance; the difference is which platform they belong to, and the shared risks are misalignment and bracket resonance.

Series 16 in-cylinder: outputs 160 / 161 / 162 SSI; Ø10 rod, cap Ø18G7, 350/530 bar, piston bore ≥12.7 mm — not the Series 17 M18×1.5 / 350/600 bar figures.
